cover http:// in text by link

Hello is there a way to find all http://* and cover it by link ? I have a text like ...
... you can find it here http://domain1.com or take a look here http://domain2.com ...
The result should be something like
... you can find it here <a href='http://domain1.com'>http://domain1.com</a> or take a look here <a href='http://domain2.com'>http://domain2.com</a> ...
I spent hours searching whole internet and did not find an solution.

Can someone hel me please ? Thanks !
